Okay first of all—this ^, politics is just another topic like news, or interests, or sports or whatever—the "here not only conflicts can arise heavily, but can also be in dislike to many other members" is an argument that can be applied to literally any topic, what? you don't see football team fans literally engage in fights or cause vandalism over what team is better? If this can be applied to any topic, and is very clearly a separate thing from the discussion (since clearly talking about the state of the elections is not the same as arguing what presidential candidate is morally correct) then the problem is in the extremism of it, which as enigma pointed out, can be dealt with like any other case, because it's the same.
Second, you don't seem to understand the difference between lack of encouragement and to not encourage: we do not want QSP to be a place of politics as much as we do not want QSP to be a place of, say, talking about the news. That doesn't mean you can't do it, it just means we do not want to give a means specific to do it, putting a place to specifically talk about something is quite literally to encourage it; tied to this is that we frankly do not care if it's a really big interest, you don't go to a library and start talking about TV there just because everyone also likes it too, places have purposes and the purpose of this server is not politics.
If you want a place to talk about politics, go to a place that is meant for talking about politics, if you think people talk too much about politics, well okay I think people talk too much about other topics too but that doesn't really give any reason to give them anything special about it
